1. A method for capturing an image, the method comprising:

  • generating a first control signal configured to cause a rolling shutter camera to capture an image of a subject, wherein the image is captured over a first time period;

    generating, at a first time point during the first time period, a second control signal configured to set a multi-spectral illumination source at a first intensity level, wherein the multi-spectral illumination source is configured to illuminate the subject; and

    generating, at a second time point during the first time period, a third control signal configured to set the multi-spectral illumination source at a second intensity level that is less than the first intensity level, wherein a portion of the image captured by the rolling shutter camera between the first and second time points includes a target feature associated with the subject.
